The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1-11. The process or period in which one image transitions to another image forms no part of the claimed design. The large circular broken line illustrates both a boundary and a display screen, the broken lines surrounding the large circular broken line illustrates an electronic device, and the remainder of the broken lines illustrate portions of the animated graphical user interface. None of the broken lines form part of the claimed design. 

CLAIM The ornamental design for a display screen with an animated graphical user interface, as shown and described.
